Auto calculators
Auto Calculators
Estimate the car number you need before you compare offers, adjust a loan or plan running costs. Start with affordability and payment checks, then use the ownership, fuel, EV, depreciation and lease-vs-buy tools when the decision needs more context.
Auto calculators run in your browser where practical. Region settings change labels, units, defaults and formatting only; they do not convert currencies or create lender quotes.

FAQs
Which car calculator should I start with?
Start with the decision in front of you: affordability for budget fit, payment or balloon payment for loan math, payoff or refinance for an existing loan, total car cost for ownership costs, fuel or EV charging for running costs, and lease vs buy or gas/petrol vs electric for comparisons.
Which calculator estimates gas or fuel cost?
Use Fuel Cost for a trip, month or year. Use Gas vs Electric when you want to compare gas or petrol fuel cost with EV charging cost side by side.
What is the difference between car affordability and car payment?
Car Payment estimates the loan payment. Car Affordability includes income, budget and running costs.
Do these calculators include insurance and fuel?
Some do. Car Payment focuses on loan payment math. Car Affordability and Total Car Cost include running-cost assumptions when you enter them.
Can I calculate EV charging costs?
Yes. Use the EV Charging Cost Calculator for charging-only estimates, Gas vs Electric for a gas/petrol fuel comparison, or Total Car Cost for broader ownership cost.
Do changing region settings convert currency?
No. Region settings change labels, units, defaults and formatting only. They do not perform exchange-rate conversion.

No. The calculators provide general estimates and are not lender quotes, financial advice or vehicle recommendations.
Do the calculators save my car numbers?
They do not require an account. Calculations run in your browser where practical, and copy or CSV exports are generated only when you start them.
